New NextEnergy 250 kW: Riello UPS's innovative transformerfree UPS family is enriched with a new...

2019年5月07日

High efficiency UPS, small footprint and higher power density.

The innovative and energy efficient UPS has been reinforced with the new NextEnergy 250 kVA, designed to meet the stringent availability needs in mission critical applications such as modern Data Centres. In these environments, a reliable and protected power supply is essential to guarantee regularity of service and business continuity. IT Managers require flexible UPSs that are adaptable to different types of architecture while at the same time ensuring maximum system availability.

Like the rest of the NextEnergy series, the new power size is a three-phase UPS that uses the most innovative transformerless ON-Line technologies with double conversion, IGBT converters, and three-level controls. Designed to meet the power requirements of the future, it offer very high energy efficiency and low operating costs. The Riello UPS research and development centre has also worked to create solutions that can provide the highest power density on the market.

Thanks to the ECS (Efficiency Control System), for example, efficiency in parallel systems is optimised based on the power required at that time.

Excellent performance

The cutting-edge technologies adopted and the careful selection of high quality and reliable components used in the production of the NextEnergy range guarantee “best in class” performance, such as unity power factor (guarantee kW = kVA), the ability to feed critical loads up to 40°C without power downgrades, and extraordinary system efficiency: NextEnergy guarantees up to 97% efficiency in double conversion mode (Online), with an increase up to and above 99% in Eco-Mode or Smart Active.

In addition, NextEnergy introduces a new mode of operation called Active Eco that allows the load to be fed from the bypass line, therefore at very high efficiency, but at the same time also working as an active filter to reduce the current harmonics produced by the users, increasing the power factor towards the entrance network. Active Eco guarantees lower energy consumption and avoids the need for any power factor correction.

Installation versatility

The NextEnergy range is able to work with or without a neutral connection. The reduced overall dimensions of the cabinet and full accessibility from the front of the UPS for all maintenance activities guarantees optimal use of space.

Maximum reliability and availability

The NextEnergy series implements all the features present in Riello UPS's existing product ranges, such as:

Parallel configuration of up to 8 units for increased redundancy (N + 1) or power;

Hot System Expansion (HSE).

Advanced communications

NextEnergy implements communication interfaces developed specifically for IT Facility Managers and Service Technicians.
